45/50 joint, 500mL.

This 500 ml vacuum trap receiving flask fits on the bottom portion of the Dewar Style Cold Trap and has a 45/50 joint. The attachment of the receiving flask to the bottom of the Dewar-style cold trap allows vapor to condense around the condenser portion of the cold trap and drip down into the receiving flask. This will help reduce pump contamination while providing a capture point for volatiles before the pump.
